RBRquadrante
The RBRlegato⁴ can integrate the RBRquadrante sensors (Fig. 9). This four-channel radiometer supports multiple radiation measurements (combinations of PAR and rad sensors) within the same sensor package.

1 RBR calibrates radiometers with NIST traceable references.
2 Out-of-band rejection is wavelength-dependent for narrow-band radiometers.
